I have an APM2, for a quad, which I accidentally soldered the wrong headers on the output pins and then removed them. This touched off several days of soldering and resoldering headers which seems to have been to no avail. I have all the wrong motors spinning, some of them will spin when engaged with the RC transmitter but not in Setup: Motors CLI mode. I think my traces are broken and intermittently being jumpered / shorted by solder. Its hard to access due to the GPS/Magnetometer sheild. I want to know if I can have it repaired or if I can easily remap the 1-4 outputs to 5-8.
Managed to fix it. I remapped the motors to channels 5-8. Interestingly I had to go deep into the code (where, I dont remember) to do this. The APM_CONFIG file remapping stuff didn't work.
It works, I believe.
